This undated handout picture released by Federal Polytechnic School of Lausanne (EPFL) shows some elements of a brain-spine interface: a microarray of electrodes on a silicon model of a primate brain, a pulse generator and spinal implant composed of 16 electrodes.
A new device has allowed two monkeys to regain use of their paralysed legs by transmitting brain signals wirelessly, bypassing their spinal cord lesions, a study released November 9 by the journal Nature said. The implantable device, called a neuroprosthetic interface, was developed by an international team led by researchers at the Federal Polytechnic School of Lausanne (EPFL) and may soon be tested as a remedy for paralysis in humans. / AFP PHOTO / EPFL / HANDOUTHANDOUT/AFP/Getty Images
